“…They also used the axial malleolar index. 1 The differences in the aforementioned studies and the studies that have reported an anterior fibular position are in the measurement technique. Mavi et al 19 and our current study examined the position of the fibula in direct relation to the tibia in the sagittal plane.…”

“…19 Despite this evidence of anteriorly positioned fibula, 3 recent studies reported the fibula to be posteriorly positioned in those with acute ankle sprains. 1,7,24 Eren et al 7 prospectively examined the position of the fibula after acute inversion ankle sprain compared with a control group of uninjured ankles. A CAT scan compared the axial malleolar index.…”

“…Since the original hypothesis proposed by Mulligan 21 there have been several studies that have examined fibular position in subjects with ankle instability. 1,6,7,17,19,24 Results have suggested both anterior 17,19 and posterior 1,7,24 positional faults in those with ankle instability. Therefore, the purpose of this study is to examine fibular position in subjects with CAI compared to a group of individuals without a history of ankle injury.…”

Study Design: Case control study. Objectives: The purpose of this study was to assess the position of the distal fibula in individuals with chronic ankle instability (CAI). Background: Recent literature has suggested that a positional fault of the fibula on the tibia may contribute to CAI; however, there is a lack of objective scientific evidence to support this claim. Methods and Measures: Thirty subjects with unilateral CAI (mean ± SD age, 20.3 ± 1.3 years) and 30 subjects with no previous history of ankle injury (mean ± SD age, 21.3 ± 3.8 years) participated in this study. Subjects completed a pair of subjective functional scales and fluoroscopic lateral images of both the right and left ankles were recorded. The distance from the anterior margin of the distal tibia to the anterior margin of the distal fibula was measured in millimeters. Nonparametric statistics were used to assess the relationship between fibular position and CAI status. Results: There were significant differences between the CAI and control group ankles (P = .045) and within the involved and uninvolved sides of the CAI group (P = .006). Those with CAI had a significantly more anterior fibular position on their involved ankle in relation to their uninvolved limb, and the ankles of the control group. Conclusions: The fibula was positioned significantly more anterior in relation to the tibia in subjects with unilateral CAI. It is unclear if repetitive bouts of ankle instability caused the anterior fibular position or if the more anterior position was a predisposing factor to injury.

Bone shapes, particularly those defining the subtalar joint (STJ), have not received much attention yet as a risk factor for developing chronic ankle instability (CAI) after sustaining a lateral ankle sprain (LAS). This study aimed to compare three‐dimensional (3D) shape variations in the STJ bones within individuals with CAI and healthy controls. 3D statistical shape models (SSMs) of the STJ bones were built to describe the bone shape variations observed within a population consisting of 26 individuals with unilateral CAI and 26 healthy controls. Using the SSMs and analysis of covariance test, age‐ and gender‐adjusted shape variations in the bones were compared within individuals with CAI and healthy controls. The mean age of the CAI patients (14 males and 12 females) and healthy controls (12 males and 14 females) was 29 (standard deviation [SD] = 11) and 36 years (SD = 11), respectively. Tali and calcanei did not significantly vary between ipsilateral CAI and their contralateral ankle. Two shape modes, one for the talus (p = 0.015, variations in the curvature of the talar lateral process and the inclination angle of the talar neck relative to the body) and one for the calcaneus (p = 0.003, variations in the medial and lateral tuberosities, and the contour of the anterior articular surface), described significant shape differences between the CAI patients and healthy controls. The CAI patients generally had flatter talar joint surfaces and a flattened calcaneal ground‐contact surface. These findings suggest that specific bone shapes may increase the risk of developing CAI after sustaining a LAS. © 2019 The Authors.
